Project Background
There are three existing 1x630MW supercritical boiler. Before denitration, the NOx concentration is about 400mg/ Nm3, and the design value of low nitrogen +SNCR emission concentration is ≤150mg/ Nm3 (6% oxygen content in dry basis).At present, it is planned to carry out ultra-low emission on the boilers, aiming to reach the NOX emission concentration in the the level of 30~50mg/Nm3 (6% oxygen content in dry basis).
